COOLING DEVICE FOR EXPLCSION-MOTORS.

Specification of Letters Patent.

.Patented Aug. 28, 1906.

I to make and use the same.

This invention relates'to certain new and useful improvements in cooling devices for explosive-motors, and has for its object to improve and perfect the construction of such devices, so that they shall be better adapted for their intended use.

The invention has special reference to aircooled motors in automobile construction, in which annular radiating flanges surround the motor-cylinders and upon which an artificially-produced air current is directed.

Reference will be had to the accompanying drawings, forming a part of this specification, and in which like numerals of reference designate corresponding parts throughout the several views, in which V Figure 1 is a view, partly in side elevation and partly in longitudinal section, of a motorvehicle embodying my improvements. Fig. 2 is a lan view of. the forward part of the vehicle-fiody with the bonnet removed, illustratingthe arrangement 'of the motor and the cooling device therefor; and Fig. 3 is a vertical longitudinal section of the forward part ofthe vehicle-frame, showing an elevation of the motor, fly and balance wheels, and the cooling-fans.

Reference-numeral 1 designates the ve hicle-frame, 2 the front wheels, and 3 the rear wheels ther,eof'.""-Upon the forward portion of the frame is mounted in the usual manner the motor, which may comprise as many cylinders as desired, though in the present case two cylinders 4 and 5 are embodied. Each of these cylinders is encircled by annular perforated radiating flanges 6, common to this type of motors. arranged a fly-wheelS, preferabl centrally Forward of and oppo site the fly-wheel 8-is mounted a balance- ,wheel 9 on a shaft 10, suitably supported from the frame. As seen in Fig. 3, the balance-'wheel receives motion from the flywheel shaft 7 through the medium of a belt Upon the motor-shaft 7 is 11, passing. around pulley 12,. secured on the said shaft 7 and wheel shaft 10.

For cooling the motor a plurality of rotary fans 14 are mountedin' advance of and opposite one end of the cylinders of the motorto direct an air-current upon the said annular flanges 6. These fans are each mounted on a spindle 15, j'ournaled in a hanger 16, secured to and supported from the vehicle-frame 1.

- nected by a belt 19 with the sheave-wheels of the other fan-spindles. The mode of simultaneously drivin said fans through the belt and sheave Wheels'is through a friction-roller 20 on the spindle of the fan adjacent the balance-Wheel 9,, which roller frictionall engages the wheel 9, receiving inotion t erefrom shield.the motor and. cooling devices, the usual bonnet 2-1"is employed. I Of course it will be understood that I do .of construction, as various changes wholly within the scopeof the claims may be made without departing from the spirit of the invention.

' The invention has special reference to artistruction and for jconvenience is herein shown applied to a series of motors or a horizontal twin air-cooled motor. "Each motor of the series is preferably provided with radiating devices suitably attached thereto and are here shown as perforated annular flanges,

may circulate; further, to one or more or a series of cooling-fans adapted to create a current of air upon and around the motor. In this particular structure the fans are placed forward of the cylinders and suitably driven for the purposes herein.

With the motors and cooling devices is asfans, a resilient supporting-frame for the motors for the purpose of absorbing the vibra tion of the motors independent of the springs of the vehicle, and to other and various features of construction hereinafter more par-. ticularly 'referred to and pointed out in the drawings.

The engine comprises the cylinder 15, which I prefer to make of cast-iron, but

sociated suitable means for actuating the xoo other material maybe em loyed,if desirable,

I I O vices w-hichlprefer to make in the form of an annular flange and of open-hearth steel and perforate the same, as shown at 17. It is to be understood, however, that with the provision of an artificial cooling means to create a current of air upon-the motor the-flan es may or may not be perforated and 0t er radiating devices employed from-Which may be obtained the same results, the main object of the fans bein to create a current of air upon the body 0 the motor. and around and? between the radiating devices. This may be accomplished by fans which will create a current of airand blow on the head and body of the motoror to draw the current to and around the motors, thoroughly cooling the motors, as is apparent, providing for eachcylinder a fanor cooling means, so as to act direct thereupon.

Having thus fully described my invention, what, I claim, and desire to secure by Letters Patent of the UnitedStates, is I 1, In combination, amultiple-cylinder engine, said cylinders having perforated radiatingflanges afiywheel on the crank-shaft, a balance-wheel,- cooling-fans supported at thehead of. each cylinder, driving connections between the fly-wheel and balanceand adjacent to said wheel, and drivin connections between the balance-wheel an fans.

2. In combination with a plurality of cylinders, and the pistons thereof, a shaft for operating said pistons, a fiy-Wheel mounted on the shaft, abalance-wheel mounted in ad- Vance of the fly-wheel, means for operating the ba1anoewheel from said shaft, a plurality of simultaneously-actuated cooling elements arranged opposite the c linders at one end alance-wheel, and means for operating said cooling elements from the balance-wheel.

3. In combination with a plurality of cylinders, short shafts disposed oppositethe forward ends thereof, sheaves and fans mounted on the said shafts, an endless, belt passing over said sheaves, a balance-wheel mounted between said cylinders, and a rollerv mounted on one of said shafts and frictionally engaging the said balance-wheel.

In testimony whereof I affix my signature in presence of two witnesses.
